PAPER-HANDLIN G DEVICE.

Specification of Letters Patent.

Patented Oct. 12, 1920.

Application filed October 28, 1919. Serial No. 334,076.

To all whom it may concern:

Be it known that I, ERVIN E. STRAWN, a citizen of the United States, and a resident of Des Moines, in the county of Polk and State of Iowa have invented a certain new and useful Paper-i-Iandling Device, of whichv the following is a specification.

The object of my invention is to provide a paper handling device of simple, durable and inexpensive construction.

It is well known that in many pr nt ng machines paper comes from the prmting mechanism with the printed surface down.

It is the object of my invention to take such paper, after the paper has been cut in sheets, and print it so that the printed side will be up and delivered to a suitable receptacle or support.

A further object is to provide such a device having simple parts whereby a plle of sheets may be readily and easily removed without stopping the operation of the press or other machine which is delivering the paper to my device.

With these and other objects 1n view my invention consists in the construction, arrangement and combination of the various parts of the device, whereby the ob ects contemplated are attained, as herelnafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, 1n which:

Figure 1 shows a top or plan view of a paper handling device embodying my 1nvention.

Fig. 2 shows a side elevation of the same.

Fig. 3 shows a detail, sectional view taken on the line 33 of Fig. 1, parts shown being omitted for more clearly illustrating the parts.

Fig. 4 shows a detail, sectional view taken on the line of Fig. 1.

Fig. 5 shows a front elevation of the device.

Fig. 6 shows a plan view of the removable paper holder, parts being omitted for the sake of clearness.

Fig. 7 shows a top or plan view of a modified form of the sliding paper platform and supporting parts therefor.

Fig. 8 shows a detail, sectional view taken on the line 8-8 of Fig. 7.

Fig. 9 shows a detail, sectional view taken on the line 99 of Fig. 7; and

Fig. 10 shows a side elevation of the pivoted lock device.

In the accompanying drawings I have used the reference numeral 10 to indicate generally the side frame members of my improved paper handling device.

The frame members 10 may be supported by brackets 11 on-the frame of a printing press or the like at such a point as to permit the delivery of the sheets of paper from the press to my device. Secured to each frame member 10 is a substantially horizontal bar 12 which projects forwardly beyond the frame members 10. The bars 12 are connected at their forward end by. means of a cross bar '13.

The frame member 10 on one side of the device has a horizontal opening 14 to permit the removal of the paper, which opening extends from the forward end of the device rearwardly as illustrated in Fig. 2.

Mounted in the frame members 10 are transverse shafts 15 and 16, the former being near the forward end of the device and the latter spaced somewhat from the rearward end of thedevice and both being near the lower portion of the device.

Mounted on the shaft 15 are rollers 17. Mounted on the shaft 16 in line with the rollers 17 are rollers 18 which are alined with the respective rollers 17.

On the alined rollers 17 and 18 are endless belts 19.

The shafts 15 and 16 are braced and connected by suitable braces 20.

Suitably mounted above the shaft 15 is a transverse shaft 21 on which are rollers 22.

Suitably mounted above the shaft 16 is a shaft 23 on which are larger respective rollers 24 alined with the rollers 22.

Spaced rearwardly and preferably slightly upwardly from the shaft 23 is a shaft 25. 7

On the shaft 25 are rollers 26, in line with the respective rollers 24, and located forwardly and upwardly with relation to the shaft 23 is another transverse shaft 27 on which are rollers 28 alined with the respective rollers 24 and 26. I

Mounted in the frame members 10 up- On the shaft 16 is another set of rollers 33. Extending around each set of alined rollers 33, 26, 30, and 24 is an endless belt neath the endless belt 34, thence forwardly aroundra roller 28, thence downwardly and around a roller 32 and thence to the roller 22.

t will be noted that the belts 34 and 35 travel around the roller 24 together, and from thence to the rollers 28 and 30 together.

On the shaft 23 is a driving device 36 such as a belt pulley, by means of which motion may be transmitted to the various rollers and endless belts.

7 Assuming that the paper is fed between the rollers 17 and 22, it is obvious that the paper will be carried between the adjacent stretches of the belts 19 and 35 from said rollers rearwardly in the machine to the rollers 24.

Assuming that the rollers 24 move in the direction indicated'by the arrow in Fig. 3,

then the other rollers will be rotated in the direction indicated by the arrow thereon. JV hen the paper reaches the rollers 33 it will be carried upwardly between the belts 34 and 35 around the rollers 24. A sheet of paper is indicated at 37 passing around the rollers 24. r

The paper then passes upwardly, and is turned over and moved forwardly in the machine between the rollers 28 and 30 and is then discharged from the endless conveyers. V

The shafts 31-and 27 and the rollers 32 and 28 are so located and are of such size that the stretches of the belt 35 between the rollers 28 and 32 are inclined downwardly and slightly forwardly, so that the rear edges of the paper discharged from between the rollers 30 and 28 will be engaged by said stretches and moved downwardly away from the rollers 28 and 30 so as to prevent any clogging of'the paper at the point of discharge from the endless belts. Extending downwardly from the frame members 12 near the forward end of the device' are'brackets 38 which support at their lower ends a transverse shaft 39.

I provide a paper receiving device comprising a bottom 40 and a forward end 41.

At the line of connection between the bot tom 40 and the end 41, the paper receiving device is mounted on'the shaft 39 by means of journals 42.

' wardly of the transverse frame member 13 is another transverse frame member 44. On the frame members 12 areears 45, shown in Fig. 4.-

Mounted in the cars 45 is a transverse shaft 46.

Pivotally supported on the shaft 39 and secured to the bottom member 40 by brackets 47 is a pawl 48 extending upwardly and having at its upper end a central recess 49. At the forward upper edge of the pawl 48 is a beveled edge 50 terminating in a point 51. At the rear upper edge of the pawl 48 is an upwardly projecting finger 52. In the frame members 13 and 44 are formed transverse slots 53 and 54 horizontally alined with each other. a

1 provide a slidable plate or table 56 havplate or table is designed to be extended through the slots 53 and 54.

In the plate 56 near the forward and rear ends, respectively, are slots 58 and 59' alined with each other longitudinally of the device and designed to 'coact with the pawl 48 in the manner hereinafter described.

I provide for use in connection with my device already described, a paper holder comprising a wall 60, secured to which is a handle 61. Extending forwardly from the opposite ends of the wall 60 are strips 62.

In the practical use of my improved device it' will be understood that the device is used in connection with a printing machine, or at least with a machine which feeds sheets of paper to the device.

Power is applied to the attachment through the driving device 36. I

The sheets of paper are fed in the manner hereinbefore described, and are dis v and slides the plate rearwardly in the machine.

The points 52 and 51 are at such heights that they tend to raise the plate slightly.

.ing at its forward end a handle 57, which As the plate is shoved rearwardly in'the pawl then limits the forward movement of the plate 56 through the following means:

adjacent to the opening 14 slots 64;. The

paper holding and removing device is then used.

The strips 62 are inserted above the bottom 40 underneath the lowermost sheet of paper. The operator can then grasp the pile of paper on the bottom 40 between his fingers, access to the paper being permitted by the slots 64, and remove the pile, which will rest on the strips 62. Thereafter the plate 56 may be pulled forwardly and removed. The paper will be engaged by the frame member 4A and will drop onto the bottom 40. As the plate 56 is withdrawn it will move the pawl 48 from its position shown in full lines in Fig. 4, to its position shown by dotted lines.

The shaft 29 may be connected with the frame member 44 by a series of wires 65,

which will prevent the paper from being blown up off the pile by a current of air.

It will be seen that with a device of this kind sheets of paper which may have been printed on their under sides may be turned over, so that they can be readily read, and with many printing machines this operation is a highly desirable one.

Furthermore the piles of sheets may be removed without stopping the operation of the machine. I

The bottom 40 need not be adjustable as shown, but it is found that if it is slanted from the point just below the discharge point of the paper downwardly and away from such discharge point, that there is less likelihood of the paper curling over on said bottom.

In Figs. 7 to 10 inclusive I have shown a slightly modified form of my device. The frame members 1O in the modified form,

which correspond to the frame members 10 of the preferred form, are connected near their forward end with a transverse frame member on which is a spring catch device 71 having an opening 72 therein, which catch device extends forwardly from the frame member 70.

At their forward ends the frame members 10 are provided with inwardly extending shoulders 73, the lower edges of which are connected bv a transverse member 7 4. The

shoulders 73 have inwardly extending pins 76. Adjacent to each shoulder 7 3 and adapted to slide longitudinally in the machine is a block 77 having in its side adjacent to the nearest shoulder 73 a beveled slot 7 8 which receives one of the pins 7 6. i

In the opposite side of each block 7 4 is a horizontal groove 79.

A plate 56 corresponding to the plate 56 already described is slidably received in the rooves 79 which are long enough to furnish proper bearings.

At its forward end the plate 56 is provided at its side edges with shoulders or lugs 80, which, when the plate 56 reaches a certain position of its rearward movement in the device, engage the respective blocks 77 forcing them rearwardly in the machine and causing them to slide upwardly on the pins 76 until the pivoted catch device 81 engages the catch member 77.

The obiect of the structure disclosed in the preferred form of the invention, whereby the plate 56 is slightly raised", is to lift the plate 56 away from the paper below it slightly when the plate 56 is inserted inits rearward position, so that if there is then resting on the bottom 40 a pile of paper which would otherwise frictionally engage the bottom 40 of the plate 56*, such frictional engagement will be avoided.

Some changes may be made in the construction and arrangement of the parts of my improved device without departing from the essential features and purposes of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included Within their scope.

I claim as my invention:
